   [IA64] perfmon.c: cleanup system-wide context when closed from another cpu
   
   - fix pfm_stop() and pfm_flush_pmds() to correctly cleanup
     in case of a system-wide context which is closed while running
     from another processor. This was leading to an assertion failure
     in pfm_loads_regs() for the next user of the PMU on the monitored
     CPU.

   [IA64] perfmon.c: file descriptor fixes
   
     - fix pfm_free_fd() to clear current->files->fd[fd] in
       case of error during PFM_CONTEXT_CREATE, i.e., undo
       the effect of fd_install(). This could cause kernel
       panic if the file descriptor gets used by error through
       perfmon.
     - fix pfm_context_create() to correctly propagate the
       return value of pfm_alloc_fd().

   [IA64] contig.c: Function find_bootmap_location has 2 bugs.
   
   Firstly, if it's done successfully, it should return -1 instead of 1
   because its caller, efi_memmap_walk, will end when find_bootmap_location
   returns a value smaller than 0.
   
   Secondly, statement "free_start = PAGE_ALIGN(rsvd_region[i].end)" should
   been moved forward. free_start needs to be initialized for every loop
   iteration.  Current implementation is buggy where initialization is
   skipped if range_end <= range_start.  Skipping initializing will leads
   to overlapping bootmap with one of the rsvd_regions and subsequently
   kernel hang at boot time.

   [IA64] Fix boot problems when using "mem=" boot parameter.
   
   My tiger-4 machine has 16GB memory. Kernel 2.6.8 fails to boot on it
   when command line parameter mem=8G, and it also fails when mem being
   set to other value, such as 7G, 10G.
   
   Basically, in function efi_memmap_walk, md->num_pages might be decreased
   if mem_limit is set, and then at the next time when efi_memmap_walk is
   called, trim_top might trim the md again because of IA64_GRANULE_SIZE
   alignment, then another md which is beyond mem_limit at the beginning
   will be chosen, and its physical page number is larger than max_pfn. Then,
   a BUG check is triggered.

   [IA64] generic_defconfig: Enable codepage/iocharset for VFAT filesystems.
   
   VFAT filesystems need to have codepages and iocharsets specified these days,
   so build some into the kernel to make it easier to mount /boot/efi on ia64
   systems.

   [IA64] Add include pagemap.h to tlb.h to fix warnings when CONFIG_SWAP=n.
   
   I noticed when building with CONFIG_SWAP=n that tlb.h gave a warning about
   some undefined symbols.  This is because it was pulling them in through
   swap.h, but when CONFIG_SWAP=n, they're no longer pulled in.  Adding
   pagemap.h to tlb.h fixes the problem.
